Biology is the study of life so a Biologist would study biology: the study of life and living things.
Answer:
Trophic level
Consumer
Producer
Explanation:
All living organisms require energy for their life processes, which they obtain by taken in food. In an ecosystem, this food is derived when organisms feed on each other. This process that eventually leads to a flow of energy within organisms is called FOOD CHAIN.
A food chain or food web always begins with a unique set of organisms called PRODUCERS. Producers are autotrophs capable of harvesting light energy from the sun and use it to produce their food (chemical) in a process called PHOTOSYNTHESIS. Other organisms called HETEROTROPHS feed on these producers to derive energy. In ecology, they are called CONSUMERS. Other consumers feed on the previous ones also to get energy.
Hence, each step of the food chain is occupied by organisms that obtain and store energy by feeding on another organism. This step is called TROPHIC LEVEL.
In a nutshell, a PRODUCER (usually plants) starts the food chain/web due to its photosynthetic ability. This producer gets eaten by an organism called CONSUMER and in the process, the energy and nutrient stored in the producers flows to the consumer. Another consumers feeds on the previous one and the energy keeps flowing. Each step of the food chain occupied by an organism that stores and transfers this energy is called TROPHIC LEVEL.
The correct answer is "<span>Wrap the thumb in gauze, place in a bag and then on ice".
Wrapping the cut-off finger in gauze or in any cloth, should be immediately placed in a bag then put on ice for it to be chilled. the thumb should not be exposed directly to the ice, or it will cause ice burns, wherein it will cause the thumb to not get sewn back. the ice is used to chill the thumb, to prevent the it from decomposing, not for freezing it. </span>
